Paper Abstract

A new approach to fiber—end microlenses fabrication is described below. The general idea is to combine laser action on glass samples ( for example, fiber ) with such mechanical forces action as stretching, twisting, bending, etc. Several different schemes for combination are suggested and tested'. The next innovation is to observe and to measure microlens geometrical and optical parameters during the laser processing and use the results for control on the microlens production. This allows one to combine producing and measurement ( testing ) operations in time and place , that provide higher productivity and an increase of available elements output. In this way, a number of new fiber—end microlenses such as arc, bulb ( spherical and non-spherical ), and elliptic shapes for beam focusing, various types of side-fiber tools, scatterers ( all—side, half—space, point, etc. ), lens—end fo— cons2 are created. Geometro—optical calculations of these fi— ber optical components ( FOC ) provided the ability to optimize their forms using an optical feed—backs of the laser technological installation.
